So first off, the source of this article being pv-magazine makes me immediately skeptical about unbiased reporting. This part really gets me though:

The availability of this electrical source is also questioned in view of the increasingly frequent droughts expected in the coming years, causing, in particular, low river flows and therefore associated problems of cooling power plants.

And availability is not a problem with renewables then? If not the central problem? Hydroelectric is probably the most reliable of the renewables, but then we have the aforementioned problem of low river flows. Droughts could even affect pumped hydro: a much-touted solution to availability problems with wind and solar. For crying out loud, present both sides of the argument fairly! /end rant

At any rate, I can get on board the idea that in terms of adding new generating capacity, renewables may be the most competitive option at the moment? They have come a long way in a short time, though they still face major challenges on the energy storage front.

But in terms of getting away from existing fossil fuel-based power generation, is nuclear not an attractive option? The infrastructure is already there, and would essentially have to be largely abandoned as sunken assets by power utilities switching to something like wind or solar right?

Consider your average coal plant. It is a centralized heat source powering steam turbines connected to large generators and a giant transformer station feeding power out over a network of high voltage transmission lines.

What is a nuclear plant then? It is a centralized heat source powering steam turbines connected to large generators and a giant transformer station feeding power out over a network of high voltage transmission lines. I'm thinking at least some of the existing hardware could be repurposed for nuclear to leverage what already exists? Am I wrong?

Pumped hydro doesn't consume nearly as much water as a thermal generator. Especially if you cover the reservoirs. It also gives you an emergency backup.

Would you prefer:

Option A where you immediately have no power when the river gets low,

Or option B where you still have power after the river gets low, but can also choose to give up the ability to have some of your power at the end of a week long cloudy period in exchange for water?
